Nowadays, the environment, economies and
social issues affect each other and cannot be considered separately. For this
reason, sustainability is an issue that is gaining importance day by day. Life
cycle sustainability assessments should be done with a holistic approach,
taking into account the environment, economies and social factors.
In this study, as a sample application,
road lighting design was done using high-pressure sodium vapor lamps (HPSVL)
and LED luminaires on an existing road, and the luminaires used in the design
were evaluated in terms of environmental, economic and social aspects. For this
purpose, calculations and evaluations have been carried out on an existing M2
lighting class road for which the LED conversion project was done. The
requirements for EN road lighting standards that were valid in Turkey were
fulfilled to a minimum extent within the scope of energy saving. In practice,
the conversion to LED was taken as a basis by simply changing the luminaire,
without changing the lighting poles in the existing installation. The use of
HPSVL and LED luminaires in an existing road lighting through a sample
application has been evaluated in terms of environmental greenhouse gas
emissions, the economics of the life cycle cost approach and the social effects
by forming opinions. From the evaluations made regarding raw materials, supply
and process information, the data was obtained from a domestic manufacturer and
evaluation was made in accordance with field studies. As a result, it has been
determined that the global warming potential of the installation with HPSVL is
44% higher than the installation with LED. In addition, as a result of the LCA
for HPSVL and LED luminaires, it was calculated that the operating cost is much
higher than the maintenance and repair, investment and salvage value costs.
